The ZJ70DB 2000HP land rig is engineered for high-performance onshore drilling, incorporating the latest in AC variable frequency drive technology. This rig delivers precise control over drawworks, rotary table, and mud pumps, ensuring optimal performance under various drilling conditions. Its fully integrated control system, featuring PLCs and touch screens, provides intelligent driller control, enhancing operational safety and efficiency.
The ZJ70DB is equipped with a single-shaft drawworks with two-speed smooth regulation, driven by a powerful 1470 kW (2000 HP) motor. The rig’s braking system combines hydraulic disc brakes with dynamic braking, offering reliable performance during both drilling and tripping operations. The mast and substructure are designed for easy transport and quick setup, with a maximum hook load capacity of 4500 kN (1,011,640 lbf), making it suitable for deep and complex well drilling.
SMKST’s ZJ70DB is fully compliant with API standards and features a modular design for easy maintenance and part replacement. This rig is an ideal choice for onshore drilling operations requiring high power and precision control.
